Batch process all your records to store structured outputs in a Chroma account. The requirements are as follows.
  • A Chroma server. You can connect to a hosted Chroma Cloud server or deploy your own server.
  • The Chroma server’s hostname or IP address, and the server’s port number. For Chroma Cloud, the host is api.trychroma.com, and the port number is 8000.
  • If you are using local Chroma, the path to the folder where you store your database.
  • The name of the tenant that you want to access on the server.
  • The name of the database that you want to access in the tenant.
  • The name of the collection that you want to access in the database.
The Chroma connector dependencies:
CLI, Python
pip install "unstructured-ingest[chroma]"
You might also need to install additional dependencies, depending on your needs. Learn more. The following environment variables:
  • CHROMA_HOST - The , represented by --host (CLI) or host (Python). Chroma Cloud uses api.trychroma.com.
  • CHROMA_PORT - The , represented by --port (CLI) or port (Python). Chroma Cloud uses port 8000.
  • CHROMA_TENANT - The name of the tenant that you want to access on the Chroma server, represented by --tenant (CLI) or tenant (Python).
  • CHROMA_DATABASE - The name of the database that you want to access in the tenant, represented by --database (CLI) or database (Python).
  • CHROMA_COLLECTION - The name of the collection that you want to access in the database, represented by --collection-name (CLI) or collection_name (Python).
Additional settings include:
  • --path (CLI) or path (Python): The location where Chroma is persisted if you are not connecting through HTTP.
  • --settings (CLI) or settings (Python): A dictionary of settings to communicate with the Chroma server, for example: '{"persist_directory":"./chroma-persist"}'.
  • --headers (CLI) or headers (Python): A dictionary of headers to send to the Chroma server, for example: '{"Authorization":"Basic()"}'.
  • --ssl (CLI) or ssl (Python): True to use SSL for the connection.
In order to use Chroma Cloud, you should have this configuration:
  • host=api.trychroma.com
  • port=8000
  • Get your tenant ID from the Chroma dashboard.
  • headers={'x-chroma-token': 'YOUR_API_KEY'}
  • ssl should be enabled.
Now call the Unstructured CLI or Python. The source connector can be any of the ones supported. This example uses the local source connector. This example sends files to Unstructured for processing by default. To process files locally instead, see the instructions at the end of this page.

For the Unstructured Ingest CLI and the Unstructured Ingest Python library, you can use the --partition-by-api option (CLI) or partition_by_api (Python) parameter to specify where files are processed:
  • To do local file processing, omit --partition-by-api (CLI) or partition_by_api (Python), or explicitly specify partition_by_api=False (Python). Local file processing does not use an Unstructured API key or API URL, so you can also omit the following, if they appear:
    • --api-key $UNSTRUCTURED_API_KEY (CLI) or api_key=os.getenv("UNSTRUCTURED_API_KEY") (Python)
    • --partition-endpoint $UNSTRUCTURED_API_URL (CLI) or partition_endpoint=os.getenv("UNSTRUCTURED_API_URL") (Python)
    • The environment variables UNSTRUCTURED_API_KEY and UNSTRUCTURED_API_URL
  • To send files to the Unstructured Partition Endpoint for processing, specify --partition-by-api (CLI) or partition_by_api=True (Python). Unstructured also requires an Unstructured API key and API URL, by adding the following:
    • --api-key $UNSTRUCTURED_API_KEY (CLI) or api_key=os.getenv("UNSTRUCTURED_API_KEY") (Python)
    • --partition-endpoint $UNSTRUCTURED_API_URL (CLI) or partition_endpoint=os.getenv("UNSTRUCTURED_API_URL") (Python)
    • The environment variables UNSTRUCTURED_API_KEY and UNSTRUCTURED_API_URL, representing your API key and API URL, respectively.
    You must specify the API URL only if you are not using the default API URL for Unstructured Ingest, which applies to Starter and Team accounts.The default API URL for Unstructured Ingest is https://api.unstructuredapp.io/general/v0/general, which is the API URL for the Unstructured Partition Endpoint. However, you should always use the URL that was provided to you when your Unstructured account was created. If you do not have this URL, email Unstructured Support at support@unstructured.io.If you do not have an API key, get one now.If you are using an Enterprise account, the process for generating Unstructured API keys, and the Unstructured API URL that you use, are different. For instructions, see your Unstructured account administrator, or email Unstructured Support at support@unstructured.io.
